ROLLING-MILL FEED-TABLE.

I SPECIFICATION forming part of Letters Patent No. 746,886, dated December 15, 1903.

' Application filed June 2, 1902. Serial No. 109,852. (No model.) I

To all whom it may. concern:

Be it known that I, EDWIN E. SLICK, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Rolling-Mill Feed-Table, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure l is a partial side, elevation showing a three-high mill providedwith my im proved feed-table,and Fig. 2 is a top plan view of the same.

My invention relates to the feed-tables used in rollingmills having passes at different levels, whether in the same or difierent sets of rolls; and it is designed to provide a simple switching mechanism which will be lifted as the metal issues from the lower-pass and will then guide the piece upwardly to an upper pass on its return movement.

In the drawings, in which I show my invention as applied to a three-high mill for rolling angles, 2, 3, and 4 represent the three rolls having suitable passes therein forshaping the metal. The first pass (indicated at a) is between the middle and upper rolls, the second pass I) is between the middle and lower rolls, the third pass 0 is between the middle and upper rolls, and the fourth pass 61 is between the middle and lower rolls.

In front of the pass I) and at the level of the pass between the middleand lower rolls is a receiving-trough 5, inthe end portion of which is placed a pair of feeding-rollers 6 6. These rollers are shown as provided with a groove shaped to lit the angle or other piece being rolled, and the lower roll is positively driven, while the upper rests by gravity upon the metal and isfri'ctionally driven- The pass inthe rollers 6 is in line with the pass b, and the metal issuing from this pass feeds along the trough 5 and into the bite of the rollers 6. As the metal thus issues from the rolls it passes beneath the lower end of and lifts a swinging trough 7, secured to a crossbar 8, pivoted in bearings 9 9, and the last end of the issuing metal is drawn out by driving the rolls 6 until its rear end passes the lower end of the trough 7. This trough, which is preferably formed of a channel shape, is cut away or beveled off at its bottom, and on reversing the movementof the rollers 6 the metal being fed back to the rolls will slide up Within the trough 7, and thus be guidedby a deflector 10 to the upper pass 0. In the form shown the metal then returns to the lower pass 61 and into the trough 11, along which it is fed by rollers 12.

The advantages of my invention result from the use of .the inclined tilting trough, which is lifted to allow the emerging metal to pass under it and then drops down to diroot the metal upwardly as it is returned to the mill.

The swinging trough may be arranged at an angle to the lower trough to deflect the metal sidewise and may lead the metal to another set of rolls, and many other changes may be made in the form and arrangement of the parts without departing from my invention.

I claim 1. The combination with a rolling-mill,having passes at diflerent levels, of a table or trough extending outwardly from a pass at a lower level, a downwardly-inclined trough or table extending down from an upper pass into the path of the metal on the lower table, and having at least a portio'n thereof arranged to swing, and mechanism for feeding the metal outwardly on the lower table to a point beyond the lowerend of the inclined trough, substantially as described.

'2. Afeedtable having a lower receivingtrough, and ;a swinging downwardly-inclined trough arranged to be lifted as'the metal onters the lower trough, the lower end of the inclined trough terminating at an intermediate point in the length of the lower trough;

anism for feeding the metal back to the rolls through the inclined trough; substantially as described.

5. A rolling-mill feed-table having a plurality of rollers arranged to receive the issuing metal between them, reversing driving connections for the rollers arranged to drive them in either direction to feed the metal out or feed it back to the rolls, and mechanism for guiding the metal to another pass on its backward feed; substantially as described.

6. The combination with a rolling-mill having a plurality of passes arranged to succes-- sively receive the metal, of a stationary roll-
